The purified substance is converted into hydrochloride and then recrystallized from ethanol/water to give 1-(1-benzyl-4-piperidinyl)-3-methylcarbostyril hydrochloride (5.8 g) as colorless needles, m.p. 274 - 276°C.

Reference Example 17

[0264] A mixture of o-aminobenzyl alcohol (20.4 g), ethanol (300 ml), 1-benzyl-4-piperidone (31.6 g) and acetic acid (40 ml) is refluxed for 30 minutes. After concentrating the reaction mixture, water is added to the resulting residue and the mixture is extracted with dichloromethane. After concentrating the extract to remove the solvent, n-hexane is added to the resulting residue and the formed crystals are separated by filtration to give 1-benzylspiro[piperidin-4,2'-(4H-1',2'-dihydro-3,1-benzoxadine)] (37.7 g), m.p. 114 - -115°C.

[1126] Using rat liver plasma membrane preparations prepared according to Ichihara's method [cf: Akira Ichihara, J. Bio. Chem., 258 9283 (1983)], the plasma membrane (50000 dpm, 2x10^-10 M) of [H]^3-Arg-vasopressin and a test compound (100 ng, 10-^{7 -} 10-⁴ M) are incubated at 37°C for 10 minutes in 100 mM Tris-HCI buffer pH: 8.0 (250 µl) containing 5 mM MgCl₂, 1mM EDTA and 0.1 % BSA. After incubation, the mixture is filtered three times using the glass filter (GF/F) so as to separate the membrane preparation combining with vasopressin and then washed with the buffer (5 ml). This glass filter is taken out and mixed with liquid scintillation cocktail. The amount of [H]^3-vasopressin combining with the membrane is measured by liquid scintillation counter and the rate of the inhibitory effect of the test compound is estimated according to the following equation.

C¹: The amount of [H]³-vasopressin combining with the membrane in the presence of the test compound (known amount).

C°: The amount of [H]³-vasopressin combining with the membrane in the absence of the test compound.

B¹: The amount of [H]^3-vasopressin combining with the membrane in the presence of the excess amount of vasopressin (10-⁶ M).

[1127] The results are espressed as IC₅₀ values, which is the concentration of the test compound required to achieve the inhibitory effect in the rate of 50 %.

Experiment 2: Anti-vasopressor activity in vivo

[1130] The spinal cord of male SD rat (weighing 300 - 400 g) is broken to give a pith rat. The blood pressure of the pith rat is measured through the cannula inserted into the femoral artery thereof by using a pressure transducer. The test compound and Arg-vasopressin are administered to the pith rat through the cannula inserted into the femoral vein. Anti-vasopressor activity of the test compound in vivo is determined according to the following equation.

Anti-vasopressor activity

tα: The increase of diastolic pressure when Arg-vasopressin (30 mU/kg) is administered intravenously.

P: The increase of diastolic pressure when Arg-vasopressin (30 mU/kg) is administered intravenouly 3 minutes after the intravenous administration of the test compound.

[1131] The results are expressed as ED₅₀ value, which is the dose of the test compound required to reduce the increase of diastolic pressure caused by the intravenous administration of Arg-vasopressin (30 mU/kg) to 50 % of its control value: P°.

[1132] The results are shown in the following Table 15.
